Troubleshooting
My system and software had been
running correctly, but suddenly
failed.
3–14
If the problem occurs when you run a program from a floppy
disk, try a different copy of the program.
If the problem is intermittent, check all cable connections
and SIMMs. Also be sure there is no debris in the keyboard
or mouse. Try to determine whether any other system
component is experiencing random failures.
If the problem occurs regularly, look for a noticeable pattern
in the failure. For example, a problem that occurs
exclusively with one file may be the result of data corruption
in the file or a faulty disk. Try recreating the data file or
using a new copy of the program in question.
If you added or modified any hardware or software, remove
the additions or changes one by one. If the problem
disappears, it was probably the result of the last change you
removed.
